Semi-Automatic Task Graph Construction for $H$ -Matrix Arithmetic

Steffen Börm, Sven Christophersen, Ronald Kriemann

A new method to construct task graphs for \mcH-matrix arithmetic is introduced, which uses the information associated with all tasks of the standard recursive \mcH-matrix algorithm…

Exploiting nested task-parallelism in the $H - LU$ factorization

Rocío Carratalá-Sáez, Sven Christophersen, José I. Aliaga +3

We address the parallelization of the LU factorization of hierarchical matrices ( $H$ -matrices) arising from boundary element methods. Our approach exploits task-paralleli…
